What is Merlin AI
Merlin AI is a browser extension and web app that brings multiple large language models into one interface. It handles summarization, content generation, coding help, and email drafting directly inside the tools you already use. The platform targets individuals and small teams who want broad AI capabilities without managing several subscriptions.
Overview
Merlin AI operates as a Chrome extension that overlays on top of websites like Gmail, LinkedIn, YouTube, and Google Search. Users can trigger the assistant with a keyboard shortcut to get instant answers, summarize long videos or documents, generate SEO content, write outreach emails, and produce code snippets. The product aggregates access to models such as GPT-4, Claude, and Gemini under a single login, which reduces the need to switch between separate AI tools. It also includes features for building custom chatbots, creating infographics from data, and drafting social media posts. The tool is designed for quick, everyday tasks rather than deep custom model training or offline processing. A free tier with limited daily queries is available alongside paid plans for heavier usage.
How to use Merlin AI
Install the Chrome extension and press the keyboard shortcut on any webpage to open the sidebar. Teams can standardize prompts and chatbots across members through the Teams plan, which includes centralized billing and usage dashboards. Common workflows include summarizing research, drafting replies in Gmail, and generating content outlines without leaving the browser.
